TERMINAL BOX.

I Specification of Letters latent.

Application filed January 9, 1914.- semi No. 811,181.

To all whom it may concern;

Be it known that I, ELDA G. SMITH, 2.

citizen of the United States, and a resident following is a specification.-

This-invention has) for its object the pro-' duction of an electrical terminal box or connection, particularly applicable to be used in connection with. electric conduits and to house terminals which are connected to the Wires in the electricconduits, and which have contacts exposed in positionto be engaged by the terminals of the plug movable into the box; and the invention consists in the novel features of construction hereinafter set forth and claimed.

In describing'this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views. Figure 1 is an elevation ofa. terminal box embodying my invention, the plug being shown as located in the box. Fig. 2 isan inverted plan of parts seen in Fig. 1, the plug being shown as shifted partly out of the box. Fig. 3 is. a longitudinal sectional view, taken centrally of Fig. 2. Fig. 4 is a cross-sectional view on line A ri, Fig. 2.

l is the box which is rectangular.in general outline, being open at 2 at its front end and at one side 3, the box having its other or rear end 4 and its other sides closed, the closed end being provided with a nipple 5 for connection with the electric conduit 6- inclosing the wires entering the box 1.

' 7 is a partition extending transversely of the interior of the box and-exposed at one edge at the open side of the box, said. partition comprising a block of insulation. The block 7 abuts against proje ions 8 on the interior of the box 1 in the pbrtion or chamber which communicateswith the nipple 5, and screws 9 1 extend transversely through the partition 7 into the projections 8 and have their heads toward the open end 20fthe box. 1 I

10 are terminals supported by the partition 7, these terminals including stems extending transversely/through the partition 7,. each-stern having a head 11 at one end which carries a contact 12 located in the portion of the box which is open at 2, at one end. The terminals also include binding devices 13 mounted on the stems and located in the chamber at the closed end of the box. The binding devices are for connection with the wires leading into the box through the conduit 6 and nipple 5.

Each binding device has aperforated base 14 mounted on the stem, and nuts 15 thread on the stem against said base. In order to prevent the binding devices from turning, their bases 14 are provided with projections 16.-which enter recesses as 17 in the partition. Usually, a strip of felt 18 is interposed betweenthe ends of the partition and the sides of the box, the strip also covering the exposed edge of the partition, said 'strip being for the purpose of forming a tight ]01Ilt. c

19 is a cover for the portion of the box between the partition 7 and the nipple or closed end of the box, the cover lapping" the edge of the partition 7 and resting on the strip of felt 18 and extending slightly in front of the partition, that is, toward the open end 2 of the box, the margin of the cover 19 toward the open end 2 of the box being deflected outwardly forming a flange 20 which forms a sto for the plug21.

The side walls 0 the box between thepartition 7 and the open end 2 of the box are formed with inturne'd flanges 22 for forming guides for the plug 21, these flanges being alined with the flange 20 of the cover 19. The cover 19 is held in position by screws, two of the screws 23 threading into the projections 8. In order that the cover may tightly fit the box,-the box is provided "with a depressed ledge 24 on which the margin of the'cover rests, and one of said screws as 25 threads into said margin.

The plug 21 is moved into and out of the box by means of a bifurcated lever 26 pivot- Patented Jan. as, 191-7.

ed to the'box and extending on opposite sides thereof, and a bail 27 connected at its opposite ends to the lever 26 and extending around the plug and engaged with hooks 28 on the plug. This feature forms no part of this invention, but forms the subject matter of my pending application, Sr. No. 787,207, filed Oct. 28, 1911, of which this application is for the most part a continuation.
